BUTTON.

SPECIFICATION formingpart of Letters Patent No. 492,418, dated February28, 1893.

Application filed March 25, 1892. Serial No. 426,422. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES T. MoOLIN- TOOK, a citizen of the UnitedStates, residing at Oil City, in the county of Venango and State ofPennsylvania, have invented a new and useful Improvement in Buttons andStuds, of which the following is a specification.

My invention relates to a large class of devices which are designed tohold together and in proper position on the person certain articles ofdress; and it is particularly adapted for connecting in a ready andreliable way two pieces of stiffened linen or cotton cloth suitablyprovided with a worked button hole in each, such as the band of acollar, or a cuff for the wrist.

In the drawings forming part of this specification, Figure 1, shows inelevation the button after insertion in the cloth. Fig. 2, is anelevation of the same after it has been made to clasp the material. Fig.3, is a vertical section of the button in its clasped condition. Fig. 4,shows in perspective the four pieces which when united by riveted pivotsform the whole; and Fig. 5, exhibits partly in elevation and partly insection a modification which will be presently described.

This invention is shown in place in Figs. 1 and 2, the cloth in eachfigure being marked 10; it consists of the plate or disk 12, forming theface of the button. To the center of this the stem or shank 14, is madefast. Upon the stem which may be square or rectangular in cross section,slides a short sleeve of metal 16, which on its end nearest the face 12,carries a secondary disk 18 parallel to said face, and

at its other end two divergent blades 20, which engage with and help toclose and open the claspin g device that holds the button in place. Thisconsists of two short arms 22, shown in all the figures, but in Fig. 4.,their formation can be Well seen. They consist of thin pieces of sheetmetal bent up on the edges to form flanges and lugs, which are piercedwith holes to connect by a riveted pivot with the stem 14, the end ofwhich is also pierced to receive said pivot. At the point 24, theaforesaid flanges are also pierced to admit of connecting the arms byriveted pivots with the divergent and flexible blades 20, for whichprovision is also made by rolling over the ends of the latter to formopenings through which the pivots pass. In this Way the arms 22 are helddefinitely in place and operated by the disks as follows.

The face and secondary disks having been separated and the two arms inconsequence brought together back to back the latter are pushed throughthe button holes in the cloth, lying over each other in the usual way.When this first step is accomplished the condition of things is reachedwhich is shown in Fig. 1, the disks being on the outside and theclasping device or shoe on the inside. To clasp the button and give itthe secure position seen in Fig. 2, it is only necessary to press stillfarther inward the face disk 12, thereby causing the stem 14 to slidethrough the sleeve 16, which is held back by the cloth 10, bearingagainst the inner or secondary disk 18, and to force apart and over thearms fulcrumed on the pivots connecting them with the flexible blades20, so as to give them the clasped position seen in Figs. 2, 3, and 5.In performing this act the thin metallic blades 20, which divergeslightly from the sleeve 16, and with it form a bifurcated hollow stemattached to the secondary disk 18, must necessarily be flexed to someextent; they therefore act as springs, causing the arms to assume thestraight position promptly and decidedly, aetuated by the elastic stemand to hold it afterward. To withdraw my button it is only necessary toslip the fingers under the points of the arms and lift them backinto theposition shown in Fig. 1, after which the button can be withdrawn. Fromthis it will be seen that the relative motions given to the two diskseffect corresponding movements in the arms and the motion that may begiven to the arms, or to one of them, is followed in like manner by theapproach or separation of the disks.

It is sometimes desirable in using my invention to operate the armsinside the cloth entirely from the front; in such cases I use the formgiven to the button in Fig. 5. This modification is in all respects likethe button described and shown, except that the inner disk is slightlylarger than the face disk, and the two when in contact as in Fig. 5,have beveled or divergent edges which incline away from each other,forming an acute angle and thereby creating an initial separation aidedby which the finger nails can be readily inserted between the disks atthe angles marked 26, in such a manner as to wedge them apart and sofacilitate their complete separation, and the simultaneous lifting ofthe arms 22, to the position seen in Fig. 1, ready for withdrawal.

It Will be seen that the introduction and securing of my button isreally a single momentary act, for pressure upon the face disk withoutstop and without special care accomplishes all that is required to enterand lock this article in place.

In the foregoing, metal has been uniformly spoken of as the materialbest suited for the manufacture of my invention, but While I believethis to be true it is obvious that a great variety of substances .can beused in whole or in part, such as ebonite, ivory, celluloid 850.

, also to a hollow, elastic, bifurcated stud sliding on the rigid stud;with two disks having divergent edges placed one behind the other toform the front part of the button, and fast respectively to each stud;substantially as shown and described.
